go get not getting latest version - v2.9.0

[rof20004]

I am trying to get faunadb-go with go get ./... but it always get this:

github.com/fauna/faunadb-go v2.0.0+incompatible // indirect
gopkg.in/fauna/faunadb-go.v2 v2.0.0

[leonidboykov]

@rof20004 you can try to get the latest version by providing a tag

go get github.com/fauna/faunadb-go@2.9.0

but thanks to Go Modules versions must have v prefix.

That would be nice to have a v2.9.0 tag for the latest version.

[rof20004]

@leonidboykov Thanks for information.

I tried this and got same version, I think the problem is like you explained, the v prefix.

This is still happening with the v2.10.0 tag unfortunately. I'm not sure how to import the module so that the right version lands in go.mod. I've tried something like import "github.com/fauna/faunadb-go/v2/faunadb" but that doesn't function. Any insights into how to import this module to get the latest?

[trevorsibanda]

@camilopayan try using in the meantime, whilst I sort this out.
go get gopkg.in/fauna/faunadb-go.v2

import "gopkg.in/fauna/faunadb-go.v2"

[camilopayan]

Thanks for the response. For now I'm sticking with 2.0, unfortunately.

When I tried import "gopkg.in/fauna/faunadb-go.v2" I got this message:

build command-line-arguments: cannot load gopkg.in/fauna/faunadb-go.v2: module gopkg.in/fauna/faunadb-go.v2@latest found (v2.0.0), but does not contain package gopkg.in/fauna/faunadb-go.v2
make: *** [build] Error 1

The tag is now correct (having the v prefix), but the go.mod file is still wrong. According to https://golang.org/cmd/go/#hdr-Module_compatibility_and_semantic_versioning the first line has to be github.com/fauna/faunadb-go/v2 instead of github.com/fauna/faunadb-go.
With the current version this leads to the followin error:

go get github.com/fauna/faunadb-go@v2.10.0
go: finding github.com/fauna/faunadb-go v2.10.0
go get github.com/fauna/faunadb-go@v2.10.0: github.com/fauna/faunadb-go@v2.10.0: invalid version: module contains a go.mod file, so major version must be compatible: should be v0 or v1, not v2

[trevorsibanda]

@exul that is correct. We have a release scheduled soon which will address this and update the documentation. > 2.10.0 all releases will follow go modules import compatibility rules.

See https://github.com/fauna/faunadb-go/tree/fix-semver

➜ go get github.com/fauna/faunadb-go@v2
go: extracting github.com/fauna/faunadb-go v2.0.0+incompatible

➜ go get gopkg.in/fauna/faunadb-go.v2
go: extracting gopkg.in/fauna/faunadb-go.v2 v2.0.0

both of these install v2.0.0 which seems to be the version from 2018 without functions for Collection among other things.

[mwildehahn]

Ah I guess you can use Class in place of Collection for the time being. FWIW this is really confusing and frustrating for someone just trying to get started with fauna.

[StarpTech]

Hi, I have the same issue as @mwildehahn described.

[StarpTech]

It looks like the current approach isn't correct:

See: https://github.com/golang/go/wiki/Modules#releasing-modules-v2-or-higher

Error:

go get github.com/fauna/faunadb-go@v2.11.0: github.com/fauna/faunadb-go@v2.11.0: invalid version: module contains a go.mod file, so major version must be compatible: should be v0 or v1, not v2

golang/go#35732

this issue cost me nearly 3 hours to find and it still persists in the latest version.
go.mod loads by default version 2.0.0 from 2018 with nonexisting f.Collection and the latest v2.12.1 version is v1.0.1-0 in go.mod
